My stay at R's place was perfect for what I needed! Check in was very easy and it was only a 25 minute drive from the DMK airport which was perfect! The bedroom and living room both have their own air con units which made it so easy to cool the apartment down quickly. I had some issues with the keypad to the apartment not working before I needed to check out (we think it was just low on batteries) and both R and his brother came to make sure I was able to get in within the hour and switched out the batteries.
I read on some of the reviews that they felt uncomfortable with all the signs regarding Thai law and daily/weekly rentals being illegal, but R was very upfront about these when I booked the place and assured me there was nothing to worry about. I lived in Thailand a few years ago as well and knew not to take these too seriously - as a foreigner, you really don't need to worry. The neighbors and the security guard were all very friendly to me!
